Note that this is from 2006. Do you have a link to the actual paper, by
Terry Shaw, of CableLabs, and Jim Martin of Clemson ?

The short answer: Badly. Based on the research, conducted by
Terry Shaw,
of CableLabs, and Jim Martin, a computer science professor at
Clemson
University, it only takes about 10 BitTorrent users bartering
files on a
node (of around 500) to double the delays experienced by
everybody else.
Especially if everybody else is using "normal priority" services,
like
e-mail or Web surfing, which is what tech people tend to call
"best-effort" traffic.
Adding more network bandwidth doesn't improve the network
experience of other network users, it just increases the
consumption by P2P users. That's why you are seeing many
universities and enterprises spending money on traffic shaping
equipment instead of more network bandwidth.
